To find the diameter of a circle given its circumference, you can use the formula:
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter. Rearranging this formula to solve for the diameter gives:
\[
d = \frac{C}{\pi}
\]
Given that the circumference \( C = 27 \) mm, we can substitute this value into the equation:
\[
d = \frac{27 \, \text{mm}}{\pi} \approx \frac{27}{3.14159} \approx 8.6 \, \text{mm}
\]
Therefore, the diameter to the nearest tenth of a mm is approximately **8.6 mm**.
